Control Algorithm Concept for AC Voltage Stabilizer Based on Hybrid Transformer with a Matrix Converter
ADVANCES IN POWER SYSTEMS AND ENERGY MANAGEMENT(2018)
摘要
This paper presents the concept of a control algorithm and a study of its properties for an AC voltage stabilizer based on a three-phase hybrid transformer with matrix converter. Presented in this paper is an approach for obtaining continuous control of the voltage magnitude and phase shift using a conventional transformer with two windings and power electronics devices, referred to as a matrix converter. By adjustment of these voltage parameters we can reduce the effects of overvoltage and voltage sags. The concept of a closed-loop control algorithm and properties of the proposed voltage stabilizers are discussed in this paper.
